Using the emerging 3GPP technologies, the communication system’s high bandwidth and low latency ensures safety and efficiency of automotive cars

NI, the developer of high-performance automated test and automated measurement systems, has released the S.E.A. C-V2X Open Loop Test System, that leverages 5G wireless cellular technology for providing high bandwidth and low latency communication for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. 

Through a software-defined approach, automotive OEMs and Tier 1 suppliers will have greater flexibility to adapt to evolving 3GPP standards. This will help in ensuring safety and efficiency of automotives.

As per a study, the safety applications enabled by V2V and V2I could eliminate or mitigate the severity of up to 80 percent of driverless car crashes. By communicating intent and gathering data from other cars about their surroundings, V2X better informs both human and autonomous driving to improve reaction time and ease decision making in vehicle interactions like cross-traffic turns and merging into traffic. 

C-V2X benefits from cellular communication like 5G which provides increased throughput and lower latency for autonomous vehicle communications, downloading high-definition maps and advanced pedestrian interactions.

“Vehicles equipped with V2X technology can give drivers and autonomous systems more time to react to dangerous situations,” said Gerd Schmitz, PhD, CEO of S.E.A. (Science and Engineering Applications) Datentechnik GmbH. “With S.E.A.’s long history of bringing new technologies to market, we recognized that research teams need to quickly understand the functionality and validate performance in a reliable and repeatable environment. Road tests are valuable, however, proving performance in the lab helps teams iterate faster and have higher confidence in the device operation under a broader set of scenarios, including hard-to-reproduce corner cases.” 

Simulating real situations

The new C-V2X solution combines software from NI Alliance Partner, S.E.A. GmbH, with NI software-defined radio (SDR) hardware to send real signals to RF and GNSS channels on C-V2X controllers and telematics control units. By combining the C-V2X and GNSS signals at the C-V2X controller, the new C-V2X solution can simulate real signals from an emergency brake warning and driving scenarios like vehicle maneuvering and traffic jam warning to help engineers characterise device performance in the lab. 

Schmitz also recognized how NI’s approach to innovation enhanced his company’s processes. “By building on the NI platform, we were able to accelerate our development by focusing on the critical V2X IP and the drive scenarios in which these systems will operate. This has enabled us to release C-V2X tools early in the design cycle to help research teams have higher confidence in their device performance and make the right recommendations to their internal customers.”

S.E.A’s offering

 S.E.A. provides the following software add-ons:

• Congestion Simulation software that emulates the surrounding environment, with up to several hundred cars, to increase the test coverage

• Channel emulation software that emulates physical distortion of radio waves to understand the signal propagation

With changing standards and new business models, engineers developing the next generation of mobility have to balance scalability and time to market. The new C-V2X solution provides both a higher level starting point to help demonstrate early success and the flexibility of the NI platform to quickly meet the market requirements.
